Martini-Marinated Steak (Filet Mignon)

Filet Mignon and Martinis; does it get any more decadent than that? The martini tenderizes the steak and gives it a nice, subtle flavor – not overpowering or alcohol-y at all. This steak will literally melt in your mouth. (The cut of the meat really isn’t as important as the quality. If you prefer a rib-eye, get that, but get the best quality meat you can afford as it really does make a difference. I like a nice, dry-aged Hereford.)
Cooking time does not include marinating time.
